If I save an incognito window that has tab groups, I can't properly restore them. If I open the extension in an incognito window and double click the collection to restore it, all the tabs open in a non-incognito window. If I open the extension in a regular window and double click a collection to restore it, it once again opens all the tabs in the non-incognito window (although in this scenario, it actually restores the tab groups).
